Question

A vendor sells hot dogs and bags of potatoe chips. A customer buys 2 hot dogs and 5 bags of potato chips for 8.00 Another customer buys 3 hot dogs and 3 bags of potato chips for 7.50 find the cost of each item

Answer 1

2d +5b = 8

3d +3b = 7.5

d + b = 7.5/3 = 2.5

d = 2.5 -b

2(2.5-b) +5b = 8

5 -2b +5b = 8

3b = 3

b = $1 per bag of chips

d = 2.5 -1 = $1.50 per hot dog
